Verdict
The clearest difference is rating: K at 4.4 against PowerMath's 3.9. PowerMath's advantage is review sentiment (20% vs 0%). On price, ratings volume, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. K sells 8 in-app purchases, starting at $1.99 per 3 months and PowerMath sells 8 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
K holds the better App Store score, 4.4 against 3.9. Both are backed by a comparable volume of ratings — 142 and 179 respectively. Written reviews complicate that: 0% of K's written reviews are positive against 20% of PowerMath's, so the app with the better star average is not the one people write more warmly about.
K ships an update every 2 weeks, PowerMath fortnightly. The most recent releases landed on October 15, 2026 and October 9, 2026 respectively.
